An affiliate of private equity investment management company, One Rock Capital Partners, has completed the acquisition of packaging company Constantia Flexibles.  

One Rock acquired Constantia from European investment company Wendel, Maxburg Capital Partners, and other shareholders. 

Headquartered in Vienna, Austria, Constantia supplies flexible packaging solutions to more than 4,000 global customers in the pharmaceutical, food, and consumer goods sectors. 

The company operates a network of 28 sites in 15 countries, with more than 7,150 employees. 

One Rock partner Kurt Beyer said: "Constantia's commitment to product innovation, sustainability and quality underscores its position as a market leader in the flexible packaging industry.  

"We look forward to working alongside Constantia's management team to enhance its operational capabilities and suite of packaging solutions to maximise its potential." 

The closure follows a definitive agreement signed by One Rock Capital with Wendel in August last year. 

The financial terms of the transaction have not been disclosed, but Wendel said that the deal brought in net proceeds of €1.097bn ($1.210bn). The total proceeds to Wendel amount to €1.121bn. 

JP Morgan and Latham & Watkins acted as the lead financial advisor and the legal advisor, respectively, to One Rock during the transaction. 

Constantia was represented by Willkie Farr & Gallagher and Evercore as legal and financial advisors, respectively.  

Constantia CEO Pim Vervaat said: "Demand for flexible packaging is increasing, and Constantia continues to strive to provide leading products and service for our customers' growing needs. As we enter this next chapter of growth, we look forward to collaborating with One Rock to continue to build on our success."
